CamcoCamper/RV Gate Valve - Features Built-In 3.5-Inch Clear Adapter & 4 Bayonet Prongs - Fits 3-Inch Sewer Fittings & Connects Easily to RV Drain Pipe (39053)

Stopped a nasty leak, looks very clean as well.

Our Gray water and black water connect just before the connection to the sewer hose. Here is how I use this item. It connects just before the sewer hose and I leave it connected all season long. Then the sewer hose connects to it. Most sewer valves leak over time. When the cap is removed to install the sewer hose nasty fluids come spilling out...not with this device! The valve is kept closed until the cap is removed and the sewer line attached. If this valve becomes polluted and difficult to close completely, just remove it and rinse it out!Also, another neat trick is to dump the black water completely. Then close this valve and open the gray water dump valve. The gray water will back flow into the black water tank helping to flush out debris. Close the gray water dump valve and open this valve to dump the black water tank again. This can be repeated as necessary as long as you have water remaining in the gray water tank. A couple months ago we got the dreaded "poop pyramid" in our black water tank and it was not emptying correctly. Using this method the clog was quickly, easily, and without mess cleared from the black water tank.Finally, when using a spray device to rinse our your black water tank, this product gives you a clear window into what is draining out of your tank. This way you know when your black tank is flushed properly.We have used these devices for several decades with no issues. We have put one on each of the campers we have owned. It is a "must have" for us.

Makes it easy to clean out tanks clear plastic lets you see quality of water as your draining

Easy to install, basically twist. The clear connector allows you to see when your takes are done draining or when you're black tank sprayer has worked when you see clear water. Helps prevent the drips when you remove the cap or connector to connect or disconnect you're sewer hose.

No matter what...it never failed. EVERY time we took the cap off of the standard evac-pipe we would get "stuff" all over our hands. Two different campers, same problem. I finally broke down and bought this one. And, NOW our hands are and stay CLEAN!There continues to be "stuff" leaking out of the standard valves/pipe, which is visible with this attachment ... However, this SHUT OFF is great! We can remover the cap and the valve holds strong.Shouldn't have waited so long to purchase.

Perfect fit!!

This is something every RV owner should have. It adds a second layer of protection when hooking up your sewer pipe. Normally, when you take of the cap, if there is liquid in the pipe, it spills out. This added gate allows you to connect your pipe, then slide open the gate! No muss, no fuss!I needed mine because my black tank gate/valve is stuck open! It was the only solution. I bought another company's valve and it was too snug and it rotated freely. The Camco is perfect for its intended use!

This is a pretty handy feature at the Final Exit of your gray and black sometimes the RV ones don't work and this one will help save you from some bad accidents
